Title: Improvements in or relating to electron discharge devices
IPC: H01J17/30
Filed: 1938-03-28
Abstract: 513,652. Thermionic valves. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. March 28,1938, No. 9437. Convention date, March 27, 1937. [Class 39 (i)] A thermionic valve of the gas filled type comprises a hollow anode surrounding a cathode to which a potential difference is applied too low to ionize the gas ; electrons are projected into the space within the anode with a velocity sufficient to ionize the gas and start the discharge from an auxiliary electrode, the stream of electrons from this electrode being controlled by a grid. In the arrangement shown the indirectly heated cathode 12 is arranged coaxially within the cylindrical anode 13 : the ends of the anode are closed except for an opening 18 covered with wire net at the bottom Opposite to the opening 18 is an indirectly heated cathode 19 carried on and connected to a plate 20 and lodged in an opening in an insulating disc 21 carried by the plate. On the disc 21 and insulated from the anode by a disc 25 is a plate 23 in the middle of which is an opening covered by a grid 24<1> corresponding to the opening 18 in the anode. Circuits for utilizing such a valve are described. Specification 447,536 is referred to. A suitable filling is helium between 250 and 300 microns.

Title: Improvements in or relating to phosphate oxidation inhibition of mineral oils
IPC: C10L1/24
Filed: 1952-04-16
Abstract: Mineral oils (which term is employed to embrace mineral oils from kerosene to heavy lubricating oil, and also petroleum fractions not normally liquid, such as petrolatum, and mineral oil compositions such as heavy duty lubricants, cutting oils, textile oils, twisted ring lubricants, extreme pressure lubricants, greases and rust preventives) are preserved against oxidation by intimate contact with an inorganic sodium phosphate containing at least two atoms of sodium per atom of phosphorus, particularly tri- or di-sodium orthophosphate.  The sodium phosphate may be ground or otherwise sub-divided and suspended or dissolved in the mineral oil, and solution may be effected with the aid of a detergent.  Alternatively, the oil may be contacted with the phosphate by passing the oil through a system where at least a portion of it is being brought continuously into intimate contact with the finely divided phosphate. Thus, the system may include a filter or filter cartridge comprising a fibrous or other porous structure impregnated with the finely divided phosphate. Suitable detergents for aiding the solution of the phosphate in the oil are the sodium and calcium salts of oil-soluble petroleum sulphonic acids, C16-C24 fatty acids, or naphthenic acids, or other alkali or alkaline earth metal salts of these acids.  The petroleum sulphonates form complexes with the phosphate; such a complex may be formed by heating an aqueous solution of the phosphate with the petroleum sulphonate to about 300 DEG  F. so that the mixture is completely dehydrated, and the complex thus formed may be added to the mineral oil.  The addition of the phosphate to kerosene, fuel oil, diesel oil and mineral lubricating oil is mentioned and the resultant composition may also contain additional antioxidants, viscosity index improvers, pour point depressants, and phenol and phenol sulphide detergents. Trisodium orthophosphate may be employed in its anhydrous form or as the dodecahydrate.  The grease composition of Specification 706,555 is disclaimed.  Specification 727,155 also is referred to.

Title: Photographic camera
IPC: G03B7/02
Filed: 1964-03-06
Abstract: 1, 045, 436. Cameras; shutter control. AGFA A.G. March 6, 1964 [March 9, 1963], No. 9533/64. Heading G2A. A camera with a built-in exposure meter has manual setting rings 7, 8 for shutter speed and diaphragm aperture respectively, ring 7 being coupled by pin 9 to rotatable axially fixed, threaded ring 16 meshing with another co-axial threaded ring 17 which is rotatably and axially movable and coupled by pin 10 to ring 8. Rings 16, 17 constitute a screw-integrating mechanism and are co-axial with the optical axis. Ring 17 has a flange 18 engaging end 19 of a spring-loaded transmission slide 20 which is connected through its rack 27 and a pinion 28 to the galvanometer 29. Rotation of shutter speed ring 7 while ring 8 is locked by a catch device, rotates ring 16, and this results in axial displacement of ring 17 which is rotationally locked to ring 8 by pin 10. The resulting linear displacement of slide 20 therefore rotates the galvanometer through pinion 28, until needle 33 rests between two reference marks visible through a window. Rotation of diaphragm ring 8 results in a further rotation of ring 17, since ring 7 is frictionally held, and the galvanometer is again set. In a modification, the pins 9, 10 engage rings 16, 17 through intermediate spring while ring 17 has an arm movable between stops on ring 16 so that damage to the follow-up control device is avoided if the sum of the displacements of rings 16, 17 exceeds the limit of deflection of needle 33 in its slot 36. The screw integrating mechanism may be made of synthetic plastics material.

Title: Method of producing gypsum plaster
Inventor: HOGGATT GILBERT A
IPC: C04B11/024
Filed: 1951-04-25
Abstract: Calcium sulphate hemihydrate in the form of thick rod-like crystals is prepared by immersing calcium sulphate dihydrate in an aqueous solution of a salt containing not less than 15 per cent anhydrous salt based on the water, and heating the solution at atmospheric pressure to a temperature up to and including the boiling temperature, the temperature and concentration being such that the vapour pressure of the solution is lower than that of calcium sulphate dihydrate in contact with semi-hydrate at the operating temperature by an amount within the range 150-1000 mms. mercury, the heating being continued till conversion is complete. Suitable salts are the sulphates, nitrates and halides of sodium, potassium, magnesium, calcium, caesium, copper and ammonia. Calcium chloride is a preferred salt, and the drawing shows a series of curves of the vapour pressure of various solutions of this salt, from 15 per cent concentration to saturated, and a curve of the vapour pressure of calcium sulphate dihydrate, plotted against temperature.  It is convenient to operate at the boiling point of the solution, preferably using concentrations of calcium chloride giving a boiling point within the range 225-230 DEG F.  The concentration of the solution which tends to change, on the one hand due to the evaporation of water, and on the other, due to the release of water of crystallization, is maintained by the addition of water or calcium chloride as may be necessary.  The converted material is finally washed with boiling water, dried up to 350 DEG F, and ground.

Abstract: The invention is directed at an additive for incorporation into a cementitious compound comprising Portland cement and water prior to the setting of the compound. The additive is comprised of a surface treated additive wherein the surfaces of the additive are treated with a substance which has a transient hydrophobic effect on the additive, which effect temporarily renders the additive more hydrophobic for a time period following the incorporation of the additive into the compound such that the water comprising the compound is less attracted to the additive during the placement of the compound and is thus available to provide workability to the compound, and such that the additive regains its natural properties following placement of the compound in order to permit the additive to participate with the compound during the curing of the compound. The invention is also directed at a process for preparing the additive and a process for preparing a cementitious compound comprised of the additive.
